Correct Answer: 391
Solution : Given: 14, 27, 52, 101, 198, ?
Multiply each number by 2 and subtract consecutive natural numbers from it to find the next term – (14 × 2) – 1 = 28 – 1 = 27; (27 × 2) – 2 = 54 – 2 = 52; (52 × 2) – 3 = 104 – 3 = 101; (101 × 2) – 4 = 202 – 4 = 198; (198 × 2) – 5 = 396 – 5 = 391
So, the missing number of the series is 391. Hence, the third option is correct.
